GEORGE A. PETERSON, OF OAKLAND, CALIFORNIA.

REINFORCED MOLDED BUILDING-BLOCK.

To all whom it may concern:

Be it known that I, GEORGE A. Pnrnnsos, a citizen of the United States, residing at Oakland, in the county of. Alameda and State of California, have invented new and useful im provements Reinforced Molded Building- Blocks, of Whlch the following is a-specir'ication. I

This'invention relates to improvements made in building blocks composed of concrete, cement, and similar compositions or mixtures, and having metal rods, bars, or wires embedded in the material as a means of reinforcing or strengthening thesame.

My invention has for its object toutilize or employ reinforcing parts or members for binding, locking or fastening one block to another in the construction of walls and other parts of a building; also, to so form and arrange the reinforcing members in each block or unit that the work of locking or fastening the blocks together in the wall can be carried on as each block or unit is placed in position, and at the same time the reinforcing members will be disposed within and throughout the finished structure in the manner best calculated to resist the strains to which the finished wall or structure shall be exposed.

To these ends and objects ,my said invention'comprises chiefly a molded buildingblock provided with lugs on its backfacc, reinforcing wires embedded in and running longitudinally through the body of the block from end to end, and wires extending through the'body and lugs transversely, or from the longitudinal wires backward and through each lug to the outside.

' The invention embraces, further, a molded 40 building-block of novel construction provided with lugs on its back-facoarnl havingreinforcing and interlocking wires running longitudinally through the body and also transversely at and through each lug to the I outside; the block having grooves and apere tures for inserting metal rods between the blocks, and also vertically through several blocks when placed in position one, upon another. The nature of the said i provements and the manner in which I proceed tofcons'truct,

apply, produce and carry out the same-are explaincd at length in the following description, the accompanymg drawings being referred to as a part of this specification.

F i ure 1 is a )ers motive-view of a art or Specification of Letters Patent.

section of a wall in the course of construction from a number of molded building blocks embodying my invention, the blocks at the end of the wall on the right being shown in section. Fig. 2 is a plan or top-view of the wall Fig. 1, on a smal er scale. Figs. 3 and 4 are horizontal sections on an enlarged scale of two blocks that may be interlocked and fastened together according to my invention, the blocks being broken away to expose the embedded wires and show the manner of fastening one block to another by the wires.

Fig. 5 is a slight modification in which the. blocks are provided with three lugs, instead block a at the time of molding, metal rods or thick wires 2 3 running longitudinally through the block, and also additional wires 4+5 in a transverse direction at each lug. The longitudinal rods or wires 2-3 run from end to end of the block and are carried to the outside; the transverse ones 4 -5 are laid at caching and are carried through the lug to the outside, either in the form of a loop with its two limbs secured to the longitudinal rods or wires 2-3, as seen in Figs. 2 and 3, oras two separate wires 4*, 5 as shown in Fig. 4. The lugs f) on the back of each block are placed at such distance apart that the blocks when laid in place one upon another, as seen inFigs. 1 and 2, will break joints between,

the lugs. By this construction the horizontal as well as the vertical joints are broken and those in the outer face ofthe wall are not opposite those in the inner face, andbesidcs, the lugs themselves cover portions of all the horizontal oints.

In the construction of block there shown the two lugs b-b are situated. on the longi--' tudinal center-line, equally distant from the top and bottom edges of the block, and at such points on that line that the distance between the end of the block and the adjacent lug will be equal to one half the length of the block. Each lug is also formed with slunting top and bottom faces giving it a wedge shaped appearance when vimved from the side, with the narrow end of the wedge joined to the block. this construction when the blocks are laid to form a wall the lugs in terlock with each other and form continuous sition, ,the space between the outer and inner faces of the wall is filled with concrete mixture thus forming a solid mass in which the 'rods 10 will be embedded. In a .wall of lighter construction having the space between the outer and inner blocks left unfilled, the additional rods 10 are omitted.

Similar grooves or depressions 9 in the "top and bottom ed es of the block are provided for placing ad 'tional rods 12 between the courses of the blocks; .and at intervals apart in the length of the block holes 13 for inserting vertical rods 14 are also formed. The

last mentioned rods 14 are so placed with relation to the interlocking lugs that the rods in theblocks of one course, being op osite to andin line with the lugs of the bloc sin the Opposite course, will pass through-the wireloopsof those lugs, or will furnish afasteningpoint around which the separate wires are twisted when separate wires and not loops are provided at the lugs. The horizontal rods 12 are laid on opposite sides of the 'erpendicular rods 14, as seen in Fig. 1,w en the former are,employed;' In that position theycontribute to the production of reater stirfness in a relatively light or thinwa 1.

At the ends of the block Where the reinforcing and interlocking wires 2-3 are brought outside, a groove or depression 16 running into the block from theback is pro-- vided for inserting a'pin or key 18 throu h the eyes or loops 17 formed in the ends of the protruding wires. This is the means by which the blocks in each horizontal course are united together at the ends, as the transverse wires 4, 5, and the vertical rods 14 are the means employed to bind the blocks together transversely of the wall.

The same features of construction are embodied inthe modification shown in Fig. 5 where the blocks are 7 wedge-shaped, interlocaing lugs, of which one is located in the middle of the block, and

one at each end; the middle one being double the thickness of those at the ends, in

order to support the end lugs of the two rovided with three thus securing the blocks together inthe same manner as the blocks in the two-lug constructions are fastened. The efiect of this construction is not only to lock the blocks in the outer-and inner courses toether againstdisplacement transversel of the wall, but also to draw them toget er, with the body of one closely against the lugs of the o posite block, by virtue of the weight of the blocks.

Other forms of lugs; such as are shown in Figs. 7 and 8 will serve the same purpose of interloclging the blocks of the outer and inner courses; but the in s with slanting top and bottom-faces have t e advantage of drawing the blocks together by virtue of their own weight.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is l 1. A molded building block having a finished face on one side to form part of'an exposed wall and on the other side having a plurality of projecting lugs, each of said lugs eing of a length less than the height of the block and arranged equi-distant between the top and'bottom edges thereof, and the aggregate width of the lugs being less than the length of the blocks, the lugs being spaced apart and of a size to engage with and set on corresponding lugs of'oppositely set blocks to constitute a continuous stud-like support for the wall between the opposite faces thereof, substantially as set forth;

2. A wall formed of molded building blocks each having Va-finished face on one side to form part of an exposed Wall, and on the other side a'plurality of lugs, the lugs being of a length less than'the height'of the block and arranged equi-dist ant between its top and l-otton edges and the aggregate Width of the lugs being less than the length of the bloclr, the lugs carried by the blocks of one face being arranged to engage with the lugs of the blocks of the .otherface, whereby the engaging lugs produce continuous sup ort- 1ng columns between the oppositely aced 3. A wall or similar structure formed of a series of duplicate blocks set back to back and spaced a art, each block being provided with a plura ity of lugs projecting from its rear face equi-distant between its top and bottom edges and having their top and bottom surfaces inclined and arranged to engage and interlock with/correspondingly shaped lugs on the blocks of theother series, substantially as set forth.

I 4. In a wall construction, the combination of two series of duplicate blocks set back to back, each blockhaving an exposed finished surface and a lug projecting from the opposite surface to engage'with a lug on theother series of blocks, and the block being also formed with a vertical aperture arranged to new forcing wires inclosed within the body of the block, comprising wires laid longitudinally from end to end and terminating in eyes on the outside, and separate wires laid trans- I versely at; intervals, and extending through to the outside wall, or similar structure, composed thg lugs offmolded building-blocks laid in outer and inner courses each block having longitudinally. laid wires inclosed within its mass from end to end, and transversely laid wires at intervals' apart extending through the back-of.

.the block to the block in the (ipposite course;

in combination with vertica y placed 'rods inserted through each block at points situafted opposite to the points at which'the transversely laid wires extend through the back of the oppositely laced blocks, as a means of fastening one b ock to the other by the transversely laid wires.

' 7-. A wall, o similar structure, composed of molded blocks laid in outer and inner courses inclosing between them a hollow space, each block provided with interlocking Y lugs on its back, and having reinforcing wires extendin through its mass comprising longitudinally aid wires running through it from end'to end to the outside and trans versely laid "wires in the lugs extending throughthe back of the same; inmornbination with vertically placed rods inserted throu h each block at points in line with the the block in the o osite course, as a b'lbcks in the outer courses to the oppositely placed blocks composing the inner coursm olded building-blocks mvided eat locking-lugs on the back, an havin reinforcing Wires embedded in its mass, inc udin are - -lpngitudinally.laid wires extending from en to end and terminating at each end on they outside in a fastening op, in combination with akey insertible through the loops of two abuttjng'blocks when the same are laid end to end, and a vertical rod insertible through each block in in? the oppositelypla'ced bloc with thelu s of when said b ocks' I aced in course back to back, 'thegsaid apertures extending vertically through it for I tie-rods and longitudinal grooves for stiffen-v ing-rods, i Y 10. A building block providedwith s acing and locking lugs on its rear face andl iaving embedded therein reinforcing wires ex tending beyond the ends of. the. block, and also binding Wire's extending through the rear of the block and continued to form wire sections of proper length for twisting, the body ofthe block having apertures extending vertically through it for tie-rods and longitudinal grooves for stiffening-rods.

11. Awall or similar structure, formedof molded building blocks provided with spacing and locking lugs on its back face, having inwardly slanting, interlocking, top and bottoI'n faces, in combination with reinforcing and binding wires extending longitudinally through the body of the block from end to end, transversely laid wires extending from the longitudinal wires through. the lugs to the outside, vertically placed rods inserted. through each block in line with the points at which the transversely laid wires or the op positely laced blocks in the structure extend to t e outside, as a means of securin one blocktoanother b the transversely laid wires, and longitudinally set rods interposed between the bottom faces of the superposed lugs and the top faces of those beneath,

and locking ugs on its face, the body of the block having apertures extending through it for tie-rod's,.reinforcing wires embedded in the block, and binding wires which extend out from the lugs to form fastening wiresof proper length fortwisting.
